Embodiment 1

[0036] One embodiment of the multi-channel composite injector of the present invention adopts a high-pressure primary fluid input from the front end, a low-pressure or no-pressure secondary fluid input from the side, and a pressurized mixed flow output from the tail. Its structure, such as figure 1 As shown, it includes a main fluid assembly 1 , an inner pipe assembly 2 , an outer pipe collar 3 and six peripheral nozzles 4 .

[0037] The center of the top (front end) of the main fluid assembly 1 is provided with a main fluid inlet pipe 11 upwards and a central nozzle 15 downwards. The lower part of the main fluid assembly 1 is provided with an annular distribution sleeve 12, see figure 2 A plurality of horizontal secondary fluid holes 13 and a plurality of vertical primary fluid holes 14 are provided on the peripheral wall of the annular distribution sleeve 12 , and the secondary fluid holes 13 and the primary fluid holes 14 are cross-isolated. The inner cavity of the annula...

Embodiment 3

[0060] In this embodiment, a high-pressure main fluid is input from the front end, a low-pressure or no-pressure secondary fluid is injected from the side, and a mixed flow is output from the tail. Its structure is as follows Figure 5 As shown, it includes the main fluid assembly 100, the inner pipe assembly 200, an outer pipe collar 300 and its extension extension pipe 300' and a central nozzle assembly 1500.

[0061]The main fluid inlet pipe 1100 is arranged at the center of the top (front end) of the main fluid assembly 100, and an annular flange is arranged at its lower end; The peripheral flanges provided are sealed butt-connected, and a diameter-expanding cavity 11100 is formed in the flared jacket 21100 at the top of the annular flow distribution sleeve 2100 . Six lateral secondary fluid holes 1300 and six vertical primary fluid holes 1400 are provided on the peripheral wall of the annular distribution sleeve 2100 , and the secondary primary fluid holes 21300 are ...

Abstract

The invention relates to a mixed flow injection device, in particular to a multiplex compound ejector which comprises a forestage compound annular ejector, a middle ejector and a rear-stage main ejector. The middle ejector is coaxially arranged in the compound annular ejector, incoming ends of the middle ejector and the compound annular ejector share a main fluid inlet pipe, and the main ejector is arranged behind the compound annular ejector and the middle ejector and concentrically connected with the compound annular ejector and the middle ejector in series to achieve integral butt joint. The multiplex compound ejector solves the technical problem that the existing ejector is simple in structure, low in ejection efficiency and insufficient in flow, and is compact in size, light in weight, high in volley rate and good in perform during mass flow.

Description

technical field [0001] The invention relates to a mixed-flow injection device, in particular to a multi-channel compound ejector for mixed fluid injection. Background technique [0002] The ejector is a device that injects a low-pressure (or no-pressure) secondary fluid with a relatively high-pressure primary fluid, and completes the suction of the secondary fluid by the primary fluid for mixed-flow injection or delivery. Since the ejector has no moving parts, it is reliable and widely used in fluid equipment in various fields. [0003] Existing typical ejectors are composed of primary fluid inlet pipe, nozzle, secondary fluid inlet, mixing chamber, throat or mixing diffuser. The secondary fluid passed into the mixing chamber is sucked into the mixing tube by the jet of the primary fluid nozzle, and the primary and secondary fluid is output from the mixing diffuser tube after being mixed and equalized. This ejector generally has a central nozzle and a single elongated mixi...
